如何在Android中的SQLite中插入大數據

Question

我試圖在SQLite中插入一個大數據，如spinner選擇的項目，日期時間和字符串。 當我運行應用程序時，我得到了：

SQLite異常：編譯插入時沒有這樣的表。 數據庫

我不知道該怎么做。

這是數據庫代碼

public class DataBase_Adapter 
{

        //Database NAme
        static final String DATABASE_NAME = "lead_management.db";

        //Database Version
        static final int DATABASE_VERSION = 1;


        // Variable to hold the database instance
        public  SQLiteDatabase db;

        // Context of the application using the database.
        private final Context context;

        // Database open/upgrade helper
        private DataBaseHelper dbHelper;

        public  DataBase_Adapter(Context _context) 
        {
            context = _context;
            dbHelper = new DataBaseHelper(context, DATABASE_NAME, null, DATABASE_VERSION);
        }

        public  DataBase_Adapter open() throws SQLException 
        {
            db = dbHelper.getWritableDatabase();
            return this;
        }

        public void close() 
        {
            db.close();
        }

        public  SQLiteDatabase getDatabaseInstance()
        {
            return db;
        }

        //Table name
    static final String TABLE_NEW_LEAD="new_lead";

        //Creating New Lead Table Columns
        private static final String KEY_NEW_LEAD_ID ="id"; 
        private static final String KEY_NEW_LEAD_NAME ="name"; 
        private static final String KEY_NEW_LEAD_EMAIL ="email";
        private static final String KEY_NEW_LEAD_MOBILE="mobile";
        private static final String KEY_NEW_LEAD_Product="define_products";
        private static final String KEY_NEW_LEAD_BUDGET="budget";
        private static final String KEY_NEW_LEAD_PRIORITY="priority";
        private static final String KEY_NEW_LEAD_STATUS="status";
        private static final String KEY_NEW_LEAD_NOTES="notes";
        private static final String KEY_NEW_LEAD_REMINDER_DATE="reminder_date";

        private static final String KEY_NEW_LEAD_ADDtoCONTACTS="add_to_contacts";


        //// SQL Statement to create a New Lead Database.
        static final String CREATE_NEW_LEAD_TABLE = "CREATE TABLE"+TABLE_NEW_LEAD+"("+KEY_NEW_LEAD_ID+"integer primary key autoincrement,"+KEY_NEW_LEAD_NAME+"TEXT,"+KEY_NEW_LEAD_EMAIL+"TEXT,"+ KEY_NEW_LEAD_MOBILE+"TEXT,"+KEY_NEW_LEAD_Product+"TEXT,"+KEY_NEW_LEAD_BUDGET+"TEXT,"+KEY_NEW_LEAD_PRIORITY+"TEXT,"+KEY_NEW_LEAD_STATUS+"TEXT,"+KEY_NEW_LEAD_NOTES+"TEXT,"+KEY_NEW_LEAD_REMINDER_DATE+"TEXT,"+KEY_NEW_LEAD_REMINDER_TIME +"TEXT,"+KEY_NEW_LEAD_ADDtoCONTACTS+"TEXT,"+")";

        //Insert New Record In New Lead Table

      public void insert_NewLead_Entry(New_Lead_BeanClass newLead_BeanClass)
      {
          SQLiteDatabase sdb = dbHelper.getWritableDatabase();

          ContentValues contentNewLead_Val=new ContentValues();
          contentNewLead_Val.put(KEY_NEW_LEAD_NAME, newLead_BeanClass.get_Name());
          contentNewLead_Val.put(KEY_NEW_LEAD_EMAIL, newLead_BeanClass.get_Email());
          contentNewLead_Val.put(KEY_NEW_LEAD_MOBILE, newLead_BeanClass.get_MobileNo());
          contentNewLead_Val.put(KEY_NEW_LEAD_Product, newLead_BeanClass.get_Product());
          contentNewLead_Val.put(KEY_NEW_LEAD_BUDGET, newLead_BeanClass.get_Budget());
          contentNewLead_Val.put(KEY_NEW_LEAD_PRIORITY, newLead_BeanClass.get_Priority());
          contentNewLead_Val.put(KEY_NEW_LEAD_STATUS, newLead_BeanClass.get_Status());
          contentNewLead_Val.put(KEY_NEW_LEAD_NOTES, newLead_BeanClass.get_Notes());
          contentNewLead_Val.put(KEY_NEW_LEAD_REMINDER_DATE, newLead_BeanClass.get_Reminder_Date());
          contentNewLead_Val.put(KEY_NEW_LEAD_REMINDER_TIME, newLead_BeanClass.get_Reminder_Time());
          contentNewLead_Val.put(KEY_NEW_LEAD_ADDtoCONTACTS, newLead_BeanClass.get_AddtoContact());

          sdb.insert(TABLE_NEW_LEAD , null , contentNewLead_Val );

          //Close The Database Connection
          sdb.close();

      }

}

這個Database Helper類

public class DataBaseHelper extends SQLiteOpenHelper
    {

   public DataBaseHelper(Context context, String name,CursorFactory factory, int version) 
        {
                   super(context, name, factory, version);
        }

        @Override
        public void onCreate(SQLiteDatabase _db) 
        {
              _db.execSQL(DataBase_Adapter.CREATE_NEW_LEAD_TABLE);
        }

        @Override
        public void onUpgrade(SQLiteDatabase _db, int _oldVersion, int _newVersion) 
        {
                   Log.w("TaskDBAdapter", "Upgrading from version " +_oldVersion + " to "  
                           +_newVersion + ", which will destroy all old data");
                _db.execSQL("DROP TABLE IF EXISTS " + DataBase_Adapter.TABLE_NEW_LEAD);

                onCreate(_db);
        }

    }




        /******************************Submit Detail Button***********************************************/

這是我的Log cat堆棧跟蹤

Answer 1

試試這樣..改變你的靜態最終字符串CREATE_NEW_LEAD_TABLE。

 CREATE_USERNAMEPASSWORD_TABLE = "CREATE TABLE "+ TABLE_UsernamePassword + "("
+ USERNAMEPASSWORD_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," 
+ USERNAMEPASSWORD_KEY_WEBTITLE + " TEXT,"
+ USERNAMEPASSWORD_KEY_WEBPASSWORD + " TEXT,"
+ USERNAMEPASSWORD_KEY_WEBNAME+" TEXT,"
+ USERNAMEPASSWORD_KEY_WEBURL +" TEXT,"
+ USERNAMEPASSWORD_KEY_WEBTYPE + " TEXT,"
+ USERNAMEPASSWORD_KEY_WEBIMAGE + " INTEGER"+");";
